Some of the categories of psychological disorders include:. The field of abnormal psychology is not without criticism. In addition to debates over the use of the term "abnormal" itself, some believe that this area has a number of shortcomings. One study found that teaching students about abnormal psychology did not reduce mental health stigma, improve attitudes toward mental illness, or increase help-seeking behaviors among students.
Abnormal psychology may focus on atypical behavior, but its focus is not to ensure that all people fit into a narrow definition of "normal.
By better understanding what is "abnormal," researchers and therapists can come up with new ways to help people live healthier and more fulfilling lives. Ever wonder what your personality type means?

The most significant problem of the stigmatization of those with psychological disorder is that it slows their recovery.
People with mental problems internalize societal attitudes about mental illness, often becoming so embarrassed or ashamed that they conceal their difficulties and fail to seek treatment. Despite all of these challenges, however, many people overcome psychological disorders and go on to lead productive lives.
People do not choose to have a mental illness. Second, we must all work to help overcome the stigma associated with disorder. Organizations such as the Canadian Mental Health Association CMHA help by working to reduce the negative impact of stigma through education, community action, and individual support. Psychologists have developed criteria that help them determine whether behaviour should be considered a psychological disorder and which of the many disorders particular behaviours indicate.
These criteria are laid out in a 1,page manual known as the Diagnostic and Statistical Manual of Mental Disorders DSM , a document that provides a common language and standard criteria for the classification of mental disorders American Psychiatric Association, The DSM is used by therapists, researchers, drug companies, health insurance companies, and policymakers in Canada and the United States to determine what services are appropriately provided for treating patients with given symptoms.
The first edition of the DSM was published in on the basis of census data and psychiatric hospital statistics. Since then, the DSM has been revised five times. The fifth edition DSM-5 is the most recent edition and was published in The DSM does not attempt to specify the exact symptoms that are required for a diagnosis. Rather, the DSM uses categories, and patients whose symptoms are similar to the description of the category are said to have that disorder. The DSM frequently uses qualifiers to indicate different levels of severity within a category.
For instance, the disorder of mental retardation can be classified as mild, moderate, or severe. Each revision of the DSM takes into consideration new knowledge as well as changes in cultural norms about disorder. Homosexuality, for example, was listed as a mental disorder in the DSM until , when it was removed in response to advocacy by politically active gay rights groups and changing social norms.
The current version of the DSM lists about disorders. Most insurance companies will not pay for therapy unless the patient has a DSM diagnosis. Two common critiques of the DSM are that the categorization system leaves quite a bit of ambiguity in diagnosis and that it covers such a wide variety of behaviours. Zack, aged seven years, has always had trouble settling down. He is easily bored and distracted.
In school, he cannot stay in his seat for very long and he frequently does not follow instructions. He is constantly fidgeting or staring into space. Zack has poor social skills and may overreact when someone accidentally bumps into him or uses one of his toys. At home, he chatters constantly and rarely settles down to do a quiet activity, such as reading a book.
But what do the symptoms mean? Does Zack simply have a lot of energy and a short attention span? Boys mature more slowly than girls at this age, and perhaps Zack will catch up in the next few years. One possibility is for the parents and teachers to work with Zack to help him be more attentive, to put up with the behaviour, and to wait it out.
ADHD is a developmental behaviour disorder characterized by problems with focus, difficulty maintaining attention, and inability to concentrate, in which symptoms start before seven years of age Canadian Mental Health Association, In adults the symptoms of ADHD include forgetfulness, difficulty paying attention to details, procrastination, disorganized work habits, and not listening to others.
The diagnosis of ADHD has quadrupled over the past 20 years, and it is now diagnosed in about one out of every 37 Canadian children. ADHD is also being diagnosed much more frequently in adolescents and adults Barkley, You might wonder what this all means.
Perhaps drug companies are also involved, because ADHD is often treated with prescription medications, including stimulants such as Ritalin. Although skeptics argue that ADHD is overdiagnosed and is a handy excuse for behavioural problems, most psychologists believe that ADHD is a real disorder that is caused by a combination of genetic and environmental factors.
Jared is able to maintain eye contact and enjoys mixing with other children, but he cannot communicate with them very well. Here he was tested by a pediatric neurologist, a psychologist, and a child psychiatrist. He diagnosed Jared with a pervasive developmental disorder , because while his comprehension and expressive language was poor, he was still able to carry out nonverbal tasks, such as drawing a picture or doing a puzzle.
The psychologist believed that the autism diagnosis was correct because, like other children with autism, Jared, has a poorly developed ability to see the world from the perspective of others, engages in unusual behaviours such as talking about trucks for hours, and responds to stimuli, such as the sound of a car or an airplane, in unusual ways.
Clearly there is something wrong with their child, but even the experts cannot agree on exactly what the problem is. Although for many years autism was thought to be primarily a socially determined disorder, in which parents who were cold, distant, and rejecting created the problem, current research suggests that biological factors are most important.
Scientists speculate that autism is caused by an unknown genetically determined brain abnormality that occurs early in development. It is likely that several different brain sites are affected Moldin, , and the search for these areas is being conducted in many scientific laboratories. The problem is that diagnosis is not exact remember the idea of categories , and the experts themselves are often unsure how to classify behaviour.
Furthermore, the appropriate classifications change with time and new knowledge. American Psychiatric Association. Barkley, R.

Examples of abnormality can take many different forms and involve different features, so that, what at first sight seem quite reasonable definitions, turns out to be quite problematic. Under this definition of abnormality, a person's trait, thinking or behavior is classified as abnormal if it is rare or statistically unusual. With this definition it is necessary to be clear about how rare a trait or behavior needs to be before we class it as abnormal. For instance, one may say that an individual who has an IQ below or above the average level of IQ in society is abnormal.
The statistical approach helps to address what is meant by normal in a statistical context. It helps us make cut — off points in terms of diagnosis. However, this definition fails to distinguish between desirable and undesirable behavior. For example, obesity is statistically normal but not associated with healthy or desirable. Conversely, high IQ is statistically abnormal, but may well be regarded as highly desirable.
Many rare behaviors or characteristics e. Some characteristics are regarded as abnormal even though they are quite frequent. The decision of where to start the "abnormal" classification is arbitrary. Who decides what is statistically rare and how do they decide?
For example, if an IQ of 70 is the cut-off point, how can we justify saying someone with 69 is abnormal, and someone with 70 normal? This definition also implies that the presence of abnormal behavior in people should be rare or statistically unusual, which is not the case. Instead, any specific abnormal behavior may be unusual, but it is not unusual for people to exhibit some form of prolonged abnormal behavior at some point in their lives, and mental disorders such as depression are actually very statistically common.
Violation of social norms is a definition of abnormality where a person's thinking or behavior is classified as abnormal if it violates the unwritten rules about what is expected or acceptable behavior in a particular social group. Their behavior may be incomprehensible to others or make others feel threatened or uncomfortable.
With this definition, it is necessary to consider the degree to which a norm is violated, the importance of that norm and the value attached by the social group to different sorts of violation e. There are a number of influences on social norms that need to be taken into account when considering the social norms definition:. For example, it is common in Southern Europe to stand much closer to strangers than in the UK.
Voice pitch and volume, touching, direction of gaze and acceptable subjects for discussion have all been found to vary between cultures. At any one time, a type of behavior might be considered normal whereas another time the same behavior could be abnormal, depending on both context and situation. For example, wearing a chicken suit in the street for a charity event would seem normal, but wearing a chicken suit for everyday activities such as shopping or going to church, it would be socially abnormal.
Time must also be taken into account, as what is considered abnormal at one time in one culture may be normal another time, even in the same culture. For example, one hundred years ago, a pregnancy outside of marriage was considered a sign of mental illness and some women were institutionalized, whereas now this is not the case.
Different people can behave in the same way and for some will be normal and others abnormal, depending on age and gender and sometimes other factors.
